Crispy Plotter is a software tool for displaying (also called plotting)
function graphs in a coordinate system. 
With Crispy Plotter you can view any graph of a
real function by entering its equation.
The main focus on Crispy Plotter is a tidy and easy-to-learn
user interface as well as good plotting performance.

Crispy Plotter has many features that help you to create, manage and export
your functions. Check the following list for its most
interesting features:
</p>
<p>
<b>Free scrolling and zooming in the coordinate system</b><br />
Viewing function graphs often involves scrolling and zooming to certain
locations of the coordinate system. In Crispy Plotter this is as easy
possible. Just "drag" the view with the left mouse button or zoom in and out
with the mouse wheel.
</p>
<p>
<b>Use and adjust parameters easily</b><br />
Parameters come in handy when you want to modify certain constants in
a function without changing the structure of the equation. Crispy Plotter
detects variables in your function as parameters as soon as you enter
the equation. They are listed in a value table, so they can be modified
easily.
</p>
<p>
<b>Display up to 12 function graphs in one coordinate system</b><br />
This is useful when you want to display several functions, which are
related to each other (for example derivatives).
</p>
<p>
<b>Export function graphs to images</b><br />
This feature makes it possible to embed function graphs into a document
of your favorite word processor or presentation software.
Crispy Plotter supports export as Windows Bitmaps (BMP),
Windows Enhanced Metafiles (EMF) and Scalable Vector graphics (SVG).
